Specification of Letters Patent.

Patented'July 23, ieifs.

Application filed May 15, 1917. Serial No. 168,836.

To all whom it may concern: 1

Be it known that we, ROBERT R. WAY and THOMAS F. MAsoN, citizens of the United States, and residents of Webb City, in the county of Jasper and State of Missouri,

have invented certain new and useful Improvements in Belters, of which the following is a specification. I 1 s 1 This invention relates to belters and itis the dominant object of the same'to'provide a. belter whichcan be easily and quickly at tached to the eriphery Or rim of a pulley or like element in a manner to secure a portion of a power transmitting belt thereto whereby, when the pulley is rotated, the belt will be automatically arranged thereabout.

Another object of the invention is to provide a belter capableof adjustment, thus, allowing the same to be used in connection with pulleys having different sizes or widths of rims. 7

Among other aims and objects of the invention' may be recited, the provision of a device of the character mentioned with a view to compactness, and in which the number of parts are few, the construction simple and the cost of production small.

Other objects will be in partobvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the construction hereinafter set forth, andthe scope of the application of which will be indicated in the following claims. r

In the accompanying drawings, wherein is shown one of. various possible embodiments of our invention; 7

Figure 1 is a side elevation partly in section of the improved belter as applied to a section of a pulley and power transmitting belt,

Fig. 2 is a transverse section through the belter, and

Fig. 3 is an end elevation thereof.

Similar characters refer to similar parts throughout" the several views of the drawings.

Referring now more specifically to the drawings, the improved belter may be stated to comprise a plurality of'telescopic clamping sections designated 1 and 2,'each of the said sections having formed upon their outer e d g larly di p d rm 3 and e arm 3 having the inner face thereof provided with a plurality of longitudinally disposed serrations 5. Upon the portion: 4 of the section 1 a lamping jaw 6 is pivotally mounted between the bifurcated extremity thereofv as at 7, and has formed upon its'upper end a laterally extending finger 8, both the finger and the jaw being provided with serrations'9, the purposeofwhich will be-subsequently apparent. Upon the telescoping portion of the clamping section 2 a rack 10 isformedwhile upon the outer end of the telescoping portion of I the clamping section 1 a pawl 11 is pivotally mounted in a slot or way 12 formed therein and is normally maintained in engagemerit-with the teeth of the rack 10 by means of a coil spring 13 arranged beneath "the free end thereof. By this means, it'will'be' appreciated, that adjustmentofthe clamping sections 1 and 2' is permitted and as a result, the belter can be used in connection with pulleys having rims of different size and widths. Further, the angular portions" 3 and 4; of the said clamping sections may be much more securely engaged with the marginal edges of the pulley rim as shown in the Fig 1, thereby preventing undue circumferential movement in use. 7

A loop or bail 14 is pivotally engaged, with a portion of the angularly disposed arm 3 of the clamping section 2 and is adapted to be engaged by a cord, chain or of the belter when other flexible connection, which connection has its remaining extremity secured to a fixed object, whereby the belter may be safely used in connection with fly wheels arranged above delicate machinery and the like without-liability of damaging the same in the event of accidental displacement of the belter. I

.In operation, when it isdesired to arrange the belt B about the rim of the pulley P, the telescopic clamping sections 1 and 2 are properly adjusted to accord with the width Q of the rim and are arranged over a portion of the said belt and then moved into en gagernent with the opposite marginal edges of-the pulley rim, the serrations 5 formed upon the arm 3 positively engaging one marginal edge while the serrated clamping jaw 6 with its laterally projecting finger 8 securely engages the opposite side edge of the pulley. By arranging the finger 8 be t een h belt- 13 and h pu l y P it will be positive connection between the same and the belt.

Manifestly, the construction shown is capable of considerable modification and such modification as is within! the :scope of our claims, we consider within the spirit of oun invention.

We claim-z l, A belter including a plurality of telescopic clamping-sections having angularly disposed arms formed on their free ends, a pivotaljaw mounted on one of said arms, one of. said sections having a rack formed on its telescopiciportion, and a pawl arranged on the,telescoping portion of the remaining section .engageable with.- said rack.

2.; A belter including a plurality of telescopic clampingsections,- means for maintaming said sections in adjusted positions, a pivotal jaw :having a laterally, extending Copieaoi this patentamay vbe obtained-for five cents each, by addressing 111182 commissionerof Patents,

scopic clamping sections having angula-rly' disposed-armsformed on their free extremities, one of said arms havmg a serrated portion, a pivotal jawmounted -v upon thelt'ree end of the remaining varm, a serrated luterally extending finger formed upon the upper portion of said-jaw, one of the clamping sectionsl having the telescoping portion thereof provided with a rack, and a spring pressed pawl mounted on the telescopingportlon of the remalnmg clamping -section.

gageable with the rack.

In testimony whereof we afiix ourv signaturesv-here-to.
